A sleeve for a medical lead includes a tubular body having a first open end and a second open end, a tubular wall extending between the first and second ends and defining a hollow center, and a longitudinal axis extending through the hollow center. A first pocket is disposed in the tubular wall and having a curved transverse cross section and a first access opening at the first open end of the tubular body. A medical lead system includes a medical lead and the sleeve configured to slide over the medical lead and be adjacent to the electrode region.

A low-profile intercranial device including a low-profile static cranial implant and a functional neurosurgical implant. The low-profile static cranial implant and the functional neurosurgical implant are virtually designed and interdigitated prior to physical assembly of the low-profile intercranial device.

An implantable medical device (IMD) may include a plurality of coils that may be used to recharge a power supply of the IMD and/or provide telemetry for the IMD. The IMD may be configured to couple all of the coils in series, such that currents that are induced by each of the coils are added together when the IMD is exposed to an electromagnetic field. The IMD may be configured to alter the coupling of the coils such that the coils are coupled in series opposition, such that currents that are induced by some coils of the IMD are opposed by currents that are induced by other coils of the IMD.

A flexible thin film metal oxide electrode fabrication methods and devices are provided and illustrated with thin film polyimide electrode formation and IrOx chemical bath deposition. Growth factors of the deposited film such as film thickness, deposition rate and quality of crystallites can be controlled by varying the solution pH, temperature and component concentrations of the bath. The methods allow for selective deposition of IrOx on a flexible substrate (e.g. polyimide electrode) where the IrOx will only coat onto an exposed metal area but not the entire device surface. This feature enables the bath process to coat the IrOx onto every individual electrode in one batch, and to ensure electrical isolation between channels. The ability to perform selective deposition, pads for external connections will not have IrOx coverage that would otherwise interfere with a soldering/bumping process.

Systems, apparatus, and methods for treating medication refractory epilepsy are disclosed. In one embodiment, a method of treating epilepsy is disclosed comprising detecting, using a first electrode array coupled to a first endovascular carrier, an electrophysiological signal of a subject. The method further comprises analyzing the electrophysiological signal using a neuromodulation unit electrically coupled to the first electrode array and stimulating an intracorporeal target of the subject using a second electrode array coupled to a second endovascular carrier implanted within a part of a bodily vessel superior to a base of the skull of the subject.

Devices, systems, and techniques are configured for identifying stimulation parameter values based on electrical stimulation that induces dyskinesia for the patient. For example, a method may include controlling, by processing circuitry, a medical device to deliver electrical stimulation to a portion of a brain of a patient, receiving, by the processing circuitry, information representative of an electrical signal sensed from the brain after delivery of the electrical stimulation, determining, by the processing circuitry and from the information representative of the electrical signal, a peak in a spectral power of the electrical signal at a second frequency lower than a first frequency of the electrical stimulation, and responsive to determining the peak in the spectral power of the electrical signal at the second frequency, performing, by the processing circuitry, an action.

Methods and devices for wireless deep brain stimulation.

A method of monitoring neural activity responsive to a stimulus in a brain, the method comprising: applying the stimulus to one or more of at least one electrode implanted in a target neural structure of the brain; detecting a resonant response from the target neural structure evoked by the stimulus at one or more of the at least one electrode in or near the target neural structure of the brain; and determining one or more waveform characteristics of the detected resonant response.

Disclosed herein are systems and methods for nerve conduction block. The systems and methods can utilize at least one rechargeable electrode. The methods can include delivering a first direct current with a first polarity to an electrode proximate nervous tissue sufficient to at least partially block conduction in the nervous tissue.

In some examples, an implantable medical device (IMD) including a hermetically sealed housing that is configured to enclose internal components. The internal components may include stimulation circuitry, processing circuitry configured to control the stimulation circuitry to deliver electrical stimulation using one or more leads received by the housing, telemetry circuitry, and a rechargeable power source. The IMD may also include a coil configured to at least one of receive energy to recharge the rechargeable power source or receive and/or transmit signals for wireless telemetry with another device, wherein the implantable medical device is configured to mount to a cranium of a patient, and wherein the coil is coiled about an axis that is approximately orthogonal to a major surface of the IMD.
